Triangle Theorems sold for X

Answer:

y = 25

Step-by-step explanation:

180 - 115 = x

x = 65

x + 90 + y = 180

65 + 90 + y = 180

y + 155 = 180

y = 25

Answer:

y = 25°

2x<9+5

2x<14

2x/2<14/2

x<7

Answer:

[tex]\boxed {\boxed {\sf x <7}}[/tex]

Step-by-step explanation:

To solve the inequality you must isolate the variable, which is x.

[tex]2x-5 < 9[/tex]

5 is being subtracted from 2x. The inverse of subtraction is addition, so add 5 to both sides of the equation.

[tex]2x-5+5 < 9+5[/tex]

[tex]2x < 14[/tex]

x is being multiplied by 2. The inverse of multiplication is division, so divide both sides by 2.

[tex]\frac {2x}{2} < \frac {14}{2}[/tex]

[tex]x <7[/tex]

The solution to this inequality is x <7

Answer:

a)

If Beth’s parents are not albino, but she has an albino brother (aa), then each parent must have the allele a. In order for someone who is not albino to be able to have an albino child of albinism, they must have type Aa.

b)

P(AA) = 0.5(0.5) = 1/4  CHANCE

P(Aa) = 0.5(0.5) = 1/4  CHANCE

P(aa) = 0.5(0.5) = 1/4   CHANCE

c)

the new probabilities are:

P(AA | not aa) = 1/3  

P(Aa | not aa) = 2/3

Step-by-step explanation:

   Given the data in the question;

a) Beth’s parents are not albino, but she has an albino brother. This implies that both of Beth’s parts have type Aa. Why?

If Beth’s parents are not albino, but she has an albino brother (aa), then each parent must have the allele a. In order for someone who is not albino to be able to have an albino child of albinism, they must have type Aa.

To be fully albino you must be aa and must also have at least one a as well as have a child with someone who also has has at least a.

b) Which of the type aa, Aa, AA could a child of Beth’s parents have? What is the probability of each type?

                             A                 a

A                         AA                Aa

a                         aA                 aa

so, Since each type is equally likely, and each is inherited independently of each other then,

P(AA) = 0.5(0.5) = 1/4  CHANCE

P(Aa) = 0.5(0.5) = 1/4  CHANCE

P(aa) = 0.5(0.5) = 1/4   CHANCE

c) Beth is not albino. What are the conditional probabilities for Beth’s possible genetic types, given this fact?

First we rule out aa, since Beth is not an Albino.

the new probabilities are:

P(AA | not aa) = 1/3  

P(Aa | not aa) = 2/3

The sandwich will cost $3.1.

Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,

Summation = addition of two or more numbers or variable

For example = 2 + 8 + 9

Subtraction = Minus of any two or more numbers with each other called subtraction.

For example = 4 - 8

Division = divide any two numbers or variable called division.

For example 4/8

Multiplication = to multiply any two or more numbers or variables called multiplication.

For example 5 × 7.

Let's say the cost of 1 drink is d while the cost of 1 sandwich is s

Now,

Given that,

A drink and a sandwich together cost $4.85.

So,

s + d = 4.85

And,

The sandwich cost $1.35 more than the drink.

So,

s = 1.35 + d

By using substitution

s = 1.35 + 4.85 - s

2s = 6.2

s = 3.1

Hence "The sandwich will cost $3.1".

Answer:

[tex]\dfrac{18(3\sqrt2-1)}{17}[/tex]

Step-by-step explanation:

The given expression is :

[tex]x=\dfrac{18}{3\sqrt2+1}[/tex]

We need to rationalize the denominator.

Multiplying and dividing both sides by [tex]3\sqrt2+1[/tex] as follows :

[tex]x=\dfrac{18}{3\sqrt2+1}\times \dfrac{3\sqrt2-1}{3\sqrt2-1}\\\\=\dfrac{18(3\sqrt2-1)}{(3\sqrt2)^2-1}\\\\=\dfrac{18(3\sqrt2-1)}{(18-1}\\\\=\dfrac{18(3\sqrt2-1)}{17}[/tex]

So, the answer is [tex]\dfrac{18(3\sqrt2-1)}{17}[/tex].

Answer:

[tex]y=\frac{13}{6}x[/tex]             [tex]y= \frac{11}{5}x[/tex]          [tex]y = \frac{21}{9}x[/tex]          [tex]y = \frac{19}{8}x[/tex]

Step-by-step explanation:

Given

The attached graph

Required

Equations with higher unit rate

First, calculate the unit rate of the graph

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Where:

[tex](x_1.y_1) = (0,0)[/tex]

[tex](x_2.y_2) = (7,15)[/tex]

So:

[tex]m = \frac{15 - 0}{7 - 0}[/tex]

[tex]m = \frac{15}{7}[/tex]

[tex]m = 2.143[/tex]

For the given options.

The unit rate is the coefficient of x

So: [tex]y = \frac{19}{8}x[/tex]

Going by the above definition of unit rate.

[tex]m = \frac{19}{8}[/tex]

[tex]m = 2.375[/tex]

[tex]y = \frac{27}{13}x[/tex]

[tex]m = \frac{27}{13}[/tex]

[tex]m = 2.077[/tex]

[tex]y = \frac{21}{9}x[/tex]

[tex]m = \frac{21}{9}[/tex]

[tex]m = 2.333[/tex]

[tex]y= \frac{11}{5}x[/tex]

[tex]m= \frac{11}{5}[/tex]

[tex]m= 2.20[/tex]

[tex]y = \frac{15}{7}x[/tex]

[tex]m = \frac{15}{7}[/tex]

[tex]m = 2.143[/tex]

[tex]y = \frac{31}{15}x[/tex]

[tex]m = \frac{31}{15}[/tex]

[tex]y = 2.067[/tex]

[tex]y=\frac{13}{6}x[/tex]

[tex]m=\frac{13}{6}[/tex]

[tex]m=2.167[/tex]

The unit rates grater than the graph's from small to large are:

[tex]y=\frac{13}{6}x[/tex]             [tex]y= \frac{11}{5}x[/tex]          [tex]y = \frac{21}{9}x[/tex]          [tex]y = \frac{19}{8}x[/tex]

[tex]m=\frac{13}{6}[/tex]              [tex]m= \frac{11}{5}[/tex]           [tex]m = \frac{21}{9}[/tex]            [tex]m = \frac{19}{8}[/tex]

Answer:

P=78,56 If something is not clear to you, just ask, I will be happy to help :)

Step-by-step explanation:

To calculate the total area of a figure, you divide it into several shapes.

P1, P2, and P3 are the area of the rectangle, P4 is the area of the square, and P5 is the area of one-quarter of the circle.

P1=a*b

P1=8*6

P1=48

P2=a*b

P2=3*2

P2=6

P3=a*b

P3=4*2

P3=8

P4=[tex]a^{2}[/tex]

P4=[tex]2^{2}[/tex]

P4=4

P5=[tex]\frac{1}{4} * r^{2} *\pi[/tex]

P5 = [tex]\frac{1}{4} * 4^{2} * \pi[/tex]

P5 =4[tex]\pi[/tex] or approximately 12,56

P = P1+P2+P3+P4+P5

P = 48+6+8+4+12,56

P=78,56

Answer:

The two numbers are 45 and 46.

Step-by-step explanation:

Given: Sum of two numbers=91

To find: Two consecutive numbers which add up to form 91

Solution:

Consecutive numbers are those numbers which have a difference of one between them.

First divide 91 into two halves, we get 45.5

Now we know 45.5+45.5=91

But the numbers should differ by one in order for them to be consecutive.

Hence we subtract 0.5 to get one number and add 0.5 to get the second number from 45.5

So, the two numbers are 45.5–0.5=45

and 45.5+0.5=46

Hence the two numbers are 45 and 46.

Answer:

[tex]\huge\boxed{\sf Solution\ Set = \{x,y\} = \{1,2\}}[/tex]

Step-by-step explanation:

3x + 4y = 11 ----------------------(1)

x = 15 - 7y   ----------------------(2)

Put Eq. (2) in (1)

3(15 - 7y) + 4y = 11

45 - 21y + 4y = 11

45 - 17y = 11

Subtracting 45 to bot sides

-17y = 11 - 45

-17y = -34

Dividing both sides by -17

y = -34 / -17

y = 2

[tex]\rule[225]{225}{2}[/tex]

Put y = 2 in Eq. (2)

x = 15 - 7(2)

x = 15 - 14

x = 1

Solution Set = {x,y} = {1,2}
